What it is
A small farm growing rainbow or brown trout from young fish (fry or fingerlings) to table size in ponds, raceways or tanks fed by a clean water source. You feed, monitor water quality, grade and harvest the fish.
Your first three steps
- Visit a working trout farm or take a short aquaculture course to learn the daily work and costs
- Check your site, water source and planning position with your local council and environment agency before spending money
- Talk to local chefs and farm shops about what size and quantity of fish they would buy
Who pays
Local restaurants, delis, farm shops, fishmongers and smokehouses, plus fishing lakes that buy fish for stocking.
How it makes money
You sell fish by weight, either whole or gutted for food, or live for stocking. Selling direct to local buyers usually earns more per kilo than selling to a wholesaler.
Skills that help
- Patience and daily routine
- Basic water quality and fish health knowledge
- Practical, physical outdoor work
- Building relationships with food buyers
Watch out for
- Check whether you need to register as an aquaculture production business and get fish health authorisation in your part of the UK
- Water abstraction and discharge permits may be needed from the environment agency for your nation, check early
- Planning permission may be needed for ponds, tanks or buildings, check with your council
- Food businesses selling fish for eating usually need registering with the local council
- Fish stock can be lost to disease, pollution, drought or predators, so check insurance options
